To ctZZ whom it may concern.-

Be it known that I, WILLIAM T. BENJAMIN, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Apparatus for Marking or Piercing Buttonhole-Flies; and I do hereby declarethefollowingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention has reference to a novel construction of machine or apparatus for quickly and easily marking the positions, in the manufacture of shoes, of the buttonholes upon the buttonhole-fly of a shoe to enable the operator to readily place the buttonholeflybencath the piercing or cutting tools of the buttonholing-machine, and thereby producing a fly with its buttonholes in the proper positions.

The invention therefore has for its principal object to provide a simple, effective, and cheap machine or apparatus provided with spacers or markers which are adapted to mark oif equidistant spaces upon the buttonhole-fly, the spacing or marking mechanism also being so constructed that its parts are easily adjustable and can be readily used to mark oft" spaces of either greater or less distance apart, as may be desirable, according to the sizes and kinds of shoes; and,'furthermore, this invention has for another purpose the production of an efiectivel "-workin a paratus or device the essential features of which are the arrangement and combination of a support provided with a piercing or marking base, in connection with which is employed a buttonhole-fly guide, a combined clamping or holding means and stripper, and any suitable number of adjustable markers or piercers arranged to be brought down upon the buttonhole-fiy to mark or pierce the places along the proper edge of the fly where the buttonholes are finally to be placed.

The invention therefore consists in the novel apparatus or machine to be employed in connection with a buttonhole-fly in the manner to be hereinafter more fully set forth for the purposes of more quickly and more economically marking upon the fly the positions where the operator is finally to place the buttonholes; and the invention, furthermore, consists in the several novel arrangements and combinations of the various parts, as well as in the details of the construction of the marking or spacing device, all of which will be finally described more in detail in the accompanying specification and then forms a part of this specification.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a front elevation of a machine or apparatus embodying the principles of my present invention, and Fig. 2 is a side View of the same. Fig. 3 is a plan or top view of the spacing or piercing mechanism on an enlarged scale. Fig. 4 isa front view of the said spacing orpiercing mechanism,the several parts of the mechanism being represented in their initial positionsbeforethe machineis operated. Fig. 5 is a similar view of the said spacing or piercing mechanism, with the combined holding and stripping means in its downwardly-forced position upon the I piercing or marking base upon which the buttonhole-fly to be marked or pierced is to be placed; and Fig. 6 is a similar view of the several parts represented in said Figs. 4 and 5, but illustrating, in addition to the downwardly-forced position of the combined holding and stripping means, the downwardly-forced positions of a number of marking or piercing tools or rods, the said views represented in Figs. 5 and 6 also showing the marking or piercing tools in differentlyadjusted positions from the positions of the said parts represented in Fig. 4:. Fig. 7 is a horizontal section'taken on line 7 7in said Fig.

1 scale, of the mechanisimthe said section being taken on line 8 S in Fig. ,4. Fig. 9 is a similar sect-ion taken on line 9 9 inFig. 3; and Fig. 1-0 is a detail section of one of the socketed slides for holding and securing in embodied in the clauses of the claim which 6, the said view representing in plan the piercforations for the reception of bolts or screws (1 by means of which the marking or piercing device can be secured upon a suitable table or bench, as will be clearly evident.

In the present instance the said marking or piercing base a is secured upon the table I),

which is provided with suitably-constructed standards or legs I), as clearly illustrated in Figs. 1 and 2 of the drawings. The said base a, as will be seen from an inspection of the several figures of the drawings, is preferably formed with the concavo-curved portion a at the front and also has a similarly-curved slot a substantially as shown andfor the purposes hereinafter more fully set forth. Extending upwardly from the upper surface of the said marking or piercing base a, at or near the respective ends of the said base, are posts or uprights a shoulder or flange a and a screw-threaded portion a arranged in a screw-threaded hole in the base a, and the post or upright is secured or held in its fixed position on said base by means of a nut a on the screw end of the post or upright and its shoulder 6& as will be clearly evident from an inspection of Figs. 8

and 9; butof course it will be understood that the said posts or uprights a may besecured in their fixed positions upon the said base a in any other desired and suitable manner. As will be seen from Figs. 1 and 2, I have pivotally secured upon a pin or bolt 0', in a bearing c, the rear end of a treadle or lever 0 which is preferably provided with a footpiece A spring g is employed for causing an upward motion of the said treadle or lever 0 when the pressure is removed from its footpiece 0 the said spring 9 being connected to the treadle or lever c and toa portion of the table or bench b, substantially in the manner represented in said Figs. 1 and 2. Pivotally attached to the said treadle or lever c by means of a pin or bolt 0 or in any other suitable manner is the lower end of a connecting-rod 0 the said rod being provided at or near its upper end with a sleeve 0 which is adjustably secured in position on said rod 0 bymeans of a set-screw c or by any other suitable means of adjustment. The said sleeve 0 also has secured thereto and preferably adjustably secured thereto by means of a set-screw c or in any other suitable manner the lower end portion of a rod or link f, the upper portion of which is arranged in and Each upright has aextends through a hole a forming a-bearing in the base a, so as to be capable of a reciprocatory movement in said hole when said rod is actuated by means of the connectingrod 0 from the treadle or lever c and the spring g. To limit the upward movement of the said rod or link f and the parts connected therewith when caused to move upward by the action of said spring 9 as soon as the footlever c has been released by the operator, I have'secured thereto by means of set-screws f or in 'any other manner a sleeve or collar f which acts as a'stop when its upper edge is brought against the under surface of the marking or piercing base a, as clearly illustrated in Fig. 8. The upper and free end of the said rod or link f is preferably provided with a screw-thread f for attaching said end of the rod or link in a screw-threaded hole of a movable plate or yoke 61 for the purpose to be presently described. Of course it will be understood that said end f of the rod or link f may otherwise be attached or secured to the said movable plate or yoke Upon the said rod or linkf is also movably and loosely arranged, so as to rest directly upon the upper surface of the marking or piercing base a, a piece of piping or a sleeve f substantially as illustrated in Fig. 8. This sleeve f acts as a stop and limits the downward movement of the vertically-movable plate or yoke d and the piercing or marking tools connected therewith when the operator applies pressure to the foot lever or treadle 0 as will be clearly evident from an inspection of the several figures of the drawings. The said movable plate or yoke cl consists, essentially, of a back piece or plate (1, which is curved, as shown, and is provided at its two ends with an upwardly-extending and tubular post (1 to enable the said plate to be movably arranged upon the upper portions a of the said posts or uprights a on the said marking or piercing base Cb. Each tubular post (1 is provided at or near its lower end portion with a forwardlyextending projection (i and secured to said projections d by means of screws d or in any other suitable manner are the two end portions of a second curved bar or plate (1 which forms a front piece of the said movable plate or yoke d. When these two plates or bars d and d have thus been secured together, a

curved slot or opening 61 is provided, which is arranged directly above and is in perfect alinement with the slot a in the said marking or piercing base a, as will be clearly evident from an inspection of Figs. 3 and 8. Each-tubular post cl is also provided at or near its lower end with a pin or screw 61 to which is attached, or rather is suspended therefrom, a link e, having an elongated slotted portion e, arranged over the pin d as shown.- The lower end of each link 6 is secured, by means of a screw or pin 6 to a block or guide It, one on each upright or post 0, on which they are movably arranged, and secured to each block or guide by means of the screws h or in any other suitable manner are the ends of a curved plate 71 which forms the combined clamping and stripping means of the apparatus for securely holding the buttonholefly of the shoe which is to be marked or pierced in position directly upon the marking or piercing base a before the downward movement of the marking or piercing mechanism, which is to be described in detailhereinafter. Arranged and encircling the said posts or uprights a between the upper surfaces of the said blocks or guides hand the lower surfaces of the tubular posts (1 of the yoke (Z are the spirally-coiled springs 70, substantially as shown in the several figures of the drawings and for the purposes to be hereinafter more fully described.

The piercing or marking mechanism consists, essentially, 'of any desirable number of slides t', which are loosely and slidably arranged in the curved slot or opening (1 by means of a pair of annular shoulders or projections t and 2' on each slide 1'. In the present construction of marking or piercing mechanism seven of such slides are employed; but it will be clearly evident that more or less of such slides may be employed, according to the number of buttonholes desired in the buttonhole-fiy of the shoe, the first slide to the right of the yoke (Z being secured in a fixed position by means of a screw i", as illustrated. Each slide 2' is also provided with a downwardly-extending portion "L in which is a recei ving-socket 2' for the reception of the upper end portion of a marking or piercing tool, as i each tool being preferably provided with the pointed ends i at their lower ends, and each tool being removably secured in the socket of the portion 2' by means of the setscrews '1'. It will therefore be evident that I can readily remove one or more of the said tools 77, as may be necessary, according to the number of markings to be made upon or in the buttonhole-fly of the shoe. The upper portion of each slide 2', as will be seen from the several figures of the drawings, is provided with a pair of cars or lugs 2', forminga space 1' between the same, and each ear or lug 2' is provided with a hole or perforation i as shown in Fig. 10. Pivotally and operatively secured upon pins or pivots Z, arranged in the said perforations of each lug or car i of the respective slides t, are thelower ends of a system of levers Z, commonly known as lazy-tongs, which are pivotally connected with each other, as shown, and are preferably provided at or near the one end of the lazy-tongs with suit-able finger-pieces, as Z for sliding the lazy-tongs laterally across the face of the movable plate or yoke 61 and setting the pointed end portions t of the marking or piercing tools the distances apart as desired by the operator or to certain graduations 77/ on the combined holding or clamping and stripper plate 7L After the lazy tongs have been set by sliding them in a lateral direction all that is necessary is to place the buttonholefly of the shoe upon the upper surface of the marking or piercing table or base a, bringing the edge of the fly against a certain gage or guide 0 at one end of the base and against the curved edges 1) of other gages or guides 19 at or near the back of the base a, substantially as indicated in dotted outline in Fig. 7. The said guide 0 may be provided with a slot 0 and may be adjustably secured in place by means of the set-screw 0 and the said guidesp may be provided with slots 17 and the set-screws p for adjustably securing them in place upon the said base a. N ow when the buttonholefly has been placed in position upon the table or base a the operator places his or her foot upon the foot-piece of the treadle c and presses it down. This operation will cause a downward sliding movement of the blocks or guides h and the plate or yoke d on the uprights or posts of, the springs 76 holding these parts in their normally relative positions (in dicated in Figs. 4 and 5) until the lower edge of the combined clam ping and stripping plate 72. is brought directly upon the buttonholefly and clamps the same in its position upon the marking or piercing base a, ready to be marked or pierced by the still descending marking or piercing tools \Vhen the com-.

bined clamping or stripping plate 71.2 has reached the position indicated in Fig. 5, the treadle or lever c has been but partially forced down, and being pressed still farther the said vertically-moving plate or yoke cl and the marking orpiercingtools connected therewith will now be forced down against the ac tion of the springs 70, there by compressing the coils thereof, as indicated in Fig. 6, and the pins (1 connected with the tubular posts (1 of the plate or yoke cl, will have moved downwardly in the slotted portions 6 of the links 6, all of which is clearly indicated in said Fig. 6. At the same time the sleeve f will limit the downward movement of the several parts, and the pointed end portions i of the marking or piercing tools 1' will have pierced the bnttonhole-iiy in the desired places and will have entered the open portion or slot a in the marking or piercing table a, as indicated in said Fig. 6. Then the pressure is taken from the treadle or lever c by the operator,

then the springs and the main spring g will cause all the vertically-movable parts of the apparatus to return to their initial and normally inoperative positions, the said plate It holding down the buttonhole-fly until the marking or piercing tools i have been withdrawn from the fly and the said plate 71. thereby acting as a stripper, as will be clearly evident.

The usefulness and advantages of the hereinabove-described apparatus are evident, for by means of the present construction I have devised a simple and operative machine for the purposes stated, and I have found by practice that the best results can be obtained with a machine or apparatus built on the genoral principles of the machine herein described and claimed, and illustrated in the accompanying drawings.
